A long time ago folks that were banned from the empire were put there. I belive Dark Liz use to keep it up. I'm not sure if any one has added to it. Something that's fun to do if your board is /p (player name) and see why they were banned.

The graveyard is no longer kept up, mainly because our numbers of banned people (and how fast they were getting banned) made the side project take up more time from other, more important moderation duties. When EMC was at its full traffic, the ban rate would have been impossible to keep up with.
